This invention relates to a matrixfassembly.

designed primarily for use in connection with the typesetting sticks of machines of the Ludlow type wherein metal is cast on the 5 faces of the assembled matrices.

matrices.

In machines of the class mentioned it has been the practice to use .sticks of two different sizes, one beingadapted for holding matrices while the other is for holding 1% stick have been made of a size adapted to that stick. This has been true of matrices for use in casting type of maximum sizes as well as type of smaller sizes and, in order that the smaller type might be printed in difi'erent positions relative. to the base line of the larger type, additional matrices have been required for the different positions. For example, one matrix has been required for use in casting a small letter a on the base line occupied by the large letter .or letters associated therewith. Another matrix has been required for casting V the letter a at a point midway between the base and the top lines of the associated large letter or letters, and a third matrix has been necessary for casting the type a on a line with the top of the large letter or letters. Obviously this has required a varied assortment of matrices and has added to the time and labor involved in properly setting the matrices in the stick or sticks.

It is an object of the persent inventiontoprovide a means whereby small matrix slugs can be supported in a stickdesigned for hold ing large matrix slugs, these added means being utilized for maintaining the small slugs orslug at any desired positions relative to the ends of the large matrix slug so that the type cast from the small matrices termined positions relative from the large matrices.

With the foregoing and other objects in view which will appear as the description to the type cast nation and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may he made within the All of the slugs for use in each will be at prede scope of what is claimed without departing from the spirit of the invention. r

In the accompanying drawings the pre ferred form of the invention has been shown.

Referring reference, 1 designates a stick of the type used in the Ludlow machine for holding 1 matrix slugs. This stick has a clamping block 2 s-lidable in one'end and adapted to be actuated by a screw 3 extending from either end of the stick. The stick diifers from the ordinary ones employed, in that grooves 4 are extended longitudinally within the top face thereof adj acent to the upper and lower walls of space 5 into which the slugs are insertible.

The stick illustrated is of the 1 size for holding matrix slugs and quads of the 1 size. One of the large size quads has been illustrated at 7 in Figure 8 and is provided I r with the usual terminal lugs 7 adapted to overlie the stick 1 when the quad is dropped into the space 5. It is to be understood that the large size matrix slugs are to be similarly made although none of them have been shown 0 in the drawings.

The small size slugs to be used in a stick are of the same general contour as the large size quads and slugs, and have been illustrated at '8. These are formed with terminal lugs 9 which, in a small size stick, would overlie the surface of the stick in the same manner as illustraed by the large size quad in Figure 8.

In order that the small slugs, and quads can be supported properly in the' large stick I 100 to the figures by characters of 70 V have devised filler slugs 10 and 11 of two different sizes. The filler slugs 10 are twice the size of the filler slugs 11 and each of them has a recess 12 providing a. seat 13 for one of the lugs 9. Each filler slug 10 has a projecting lug 14; for overlying the stick and from this lug 14. depen'dsa lip 15 adapted to project, into the adjacent groove 4. Where large filler slugs 10 are employed the small matrix slugs can be supported at either the top or the bottom of the space 5. In thedrawmgsmatriX slugs for casting type $125.50? have been shown posltioned adgacent'to the upper side of the space 5 while thelarge filler. lugs 10.

have been interposed between the lower side of the space 5 and the matrix L sembling these slugs 8 and 10 the filler slugs 10 are first inserted into the inverted stick 1 at the proper points so that lips '15 will enter the adjacent groove 4. Thus the filler slugs will be properly held against displacement and the space left between them and the far.

side of the space 5 will be such as to receive the small slugs 8. One lug 9 of each-of these slugs will rest on the stick, as shown in Figures 3, 4, and 5, while the other lug 9 will rest oln the seat 13 provided therefor bythe fil'ler s ug.

Where narrow matrix slugs ofthe small size are used, as shown forexample at 16, a single filler slug 17 can be used in connection with all of them and with one or more quads 18 of the smaller size. Filler slug 17 is of the same contour as the slug 10 and differs therefrom solely in its length which can be suited to the number of slugs 16 and 18 with which it is to be used. Obviously there is no limitation as to the length of the filler slugs employed.

Should it be desired to support the'small size matrix slugs in intermediate positions, as shown forexample at 19in Figures2, 6 and 7, it wouldthen be necessary to use twoof the smaller or half-size filler slugs '11. These half-size filler slugs are also recessed to provide seats 20 and have lugs 21 from which depend lips 22. The half-size filler slugs are inserted in the space 5. at the top and bottom thereof so thatthe-lips 22 will enter grooves 4 at the proper points. Thus the filler slugs will be properly supported and a small size slug 19 can then be dropped into the space between these slugs 11 with its terminal lugs 9 resting on the seats 20. As a result of this arrangement the small matrix slugs will be held centered in the space 5 pro-I vided for large matrix slugs. After the'various matrix slugs, filler slugs and quads, both large and small, have been assembled in the stick they are all pressed together tightly by means of block 2 andscrew 3 and thereafter a type 23 is cast on the mat faces of the slugs and subsequently canbe used for printing purposes.

Although no 1 1; matrix slugs have been illustrated. it is to be understood that theyslugs. 1 In as-v aser/a can be assembled with the smaller matrix slugs should such a type combination be desired.

. By using one size stick for both sizes of slugs considerable time and labor is saved in assembling the slugs in a machine of the Ludlow type. I
